I have 3 of them going on my red sea 625xxl. I'm only a softy guy right now because every SPS I've put in the tank dies within 7 days. Trying to figure that out on the other forum because we've got it narrowed to chemistry not lighting. Here's a couple pictures of my tank and the schedule I'm running.
PS--I'm sold on Neptune and Red Sea stuff. I use the WAV pumps on the back wall, RS LEDs, and the Neptune. Been running this for 3 years and softies love it!
